Prif nodwedd y gronfa hon yw'r dyddiad, mis neu'r flwyddyn penodol sydd yn sail i'ch cofnod. Mae'r tywydd wrth gwrs yn rhywbeth sydd yn digwydd "rwan", pryd bynnag yw neu oedd "rwan" i'r cofnodwr gwreiddiol; y bore yma efallai, diwrnod arbennig yn eich plentyndod, neu sylw mewn dyddiadur dwy ganrif yn ôl yn sir Feirionnydd.... efallai. Neu efallai bod cysylltiad y sylw a'r tywydd yn ymddangosiadol wan iawn: tylluan wen yn hela am dri o'r gloch y prynhawn ar ddyddiad arbennig o Chwefror; clywed y gog yn canu ddiwedd mis Mawrth; teilo cae at datws ddechrau’r gwanwyn. Tywydd....? efallai! Ffenoleg...? yn bendant.
Mae'r Tywyddiadur yn rhyngweithiol - hynny yw, mi allwch rhoi gwybodaeth i fewn iddo, neu chael gwybodaeth allan. Y cam cyntaf y byddwch yn cymryd wrth fentro ar y dudalen hon felly fydd dewis pa un rydych am ei wneud.... Chwilio ynteu Mewnbynnu (blychod chwilio ar y chwith mewn glas, blychod mewnbynnu ar y dde mewn coch).
(Ewch i’r gwaelod am ganllawiau cychwynnol).
CHWILIO: Chi biau’r dewis: mis neu gyfnod arbennig efallai, blwyddyn, gair (neu ddau air), neu ddiwrnod penodol (treiwch ddyddiad eich pen-blwydd). Cewch wneud cyfuniad o rhain.
MEWNBYNNU: Trwy fewnbynnu cewch ychwanegu at y gronfa a chreu adnodd mwy cynhwysfawr fyth i ymchwilwyr fel chi. Dim ond tri amod sydd ar eich cofnod: ei fod yn cynnwys rhyw fath o ddyddiad, lleoliad (bras neu fanwl), a bod y cofnod rhywfodd yn gysylltiedig â’r amgylchedd.
